论文摘要
该注释旨在作为Dahmani,Guirardel,Osin和Lamy Cantat的两部作品的介绍。我们为作用在简单树上的小组提供了两个取消定理的证明。我们讨论了在任何地面场上对平面多项式自动形态的应用。
This note is intended as an introduction to two previous works respectively by Dahmani, Guirardel, Osin, and by Cantat, Lamy. We give two proofs of a Small Cancellation Theorem for groups acting on a simplicial tree. We discuss the application to the group of plane polynomial automorphisms over any ground field.
